Systems and Methods for Performing Global Dimming in Artificial Reality Systems - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240347013 titled 'Systems and Methods for Performing Global Dimming in Artificial Reality Systems

Simplified Explanation: This patent application describes a computing system that adjusts the color values and backlight intensity of image frames shown on a display with multiple backlight zones based on statistics computed from previous frames.

  • The computing system receives a first image frame and computes statistics for the backlight zones.
  • It then calculates a global dimming gain to adjust the color values and backlight intensity of the next image frame.
  • Using this global dimming gain, the system adjusts the color values and backlight intensity of the second image frame.

Key Features and Innovation:

  • Adaptive adjustment of color values and backlight intensity based on previous frame statistics.
  • Global dimming gain calculation for optimal display quality.
  • Efficient utilization of backlight zones for improved image quality.

Potential Applications: This technology can be applied in:

  • Smart TVs
  • Monitors
  • Digital signage displays

Problems Solved:

  • Inconsistent display quality across different backlight zones.
  • Wasted energy due to unnecessary backlight intensity.

Benefits:

  • Enhanced image quality.
  • Energy efficiency.
  • Improved user experience.

Commercial Applications: Title: Adaptive Display Technology for Enhanced Visual Experience This technology can be utilized in various commercial settings such as:

  • Entertainment venues
  • Retail stores
  • Control rooms

Prior Art: Prior art related to this technology may include research on dynamic backlight adjustment in display systems.

Frequently Updated Research: Stay updated on advancements in display technology and image processing algorithms for improved visual experiences.

Questions about Adaptive Display Technology: 1. How does this technology improve energy efficiency in display systems? 2. What are the potential challenges in implementing this technology in different types of displays?


Original Abstract Submitted

in particular embodiments, a computing system may receive receiving a first image frame of a sequence of image frames to be shown on a display having a plurality of backlight zones. the computing system may compute backlight unit statistics of the first image frame. the backlight unit statistics may represent grayscale levels for the plurality of backlight zones. the computing system may compute a global dimming gain for adjusting color values and backlight unit intensity of a second image frame of the sequence of image frames based on the backlight unit statistics of the first image frame. the computing system may adjust, using the global dimming gain, the color values and the backlight unit intensity of the second image frame.
